Abstract (from CDS):

New spectroscopic observations of Nova Cygni 1992 (V1974 Cyg) carried out in 1994-95 have shown a progressive decrease of the ionization level, made evident by the fading or disappearance of the emission lines of [Ne V], [Ne III], [Fe VII], [Fe VI] and [O III], which were outstanding in the 1992-93 spectra. An echelle spectrum obtained at Asiago in October 1995 clearly shows the complexity of the velocity field of the nova. By scanning three spectra in 1994-95 perpendicular to the direction of the dispersion along Hα, it has been found all around the nova an extended emission nebulosity, having an upper diameter of about 3arcmin in July 1994 and nearly 4arcmin in May and October 1995. By assuming that the excitation of this nebulosity was due to the ultraviolet radiation emitted by the nova in the 1992 outburst, we found the distance to the nova about 1.9±0.1kpc.
